Two prototype low-cost systems have teen developed for air crew training. These systems provide instruction in cockpit procedures and various flight tasks at approximately one quarter the cost of conventional training approaches. Savings are estimated to be $1.5 million for one of the low-cost systems, a cockpit procedures trainer for the SH-3H aircraft; $3.2 million savings are estimated for the other low-cost system, a part task trainer for the EA-3B aircraft. This report discusses the cost-saving approaches and the acceptability and cost effectiveness associated with these two developments. Efforts to translate the low-cost approaches to several "follow-on" production systems are discussed. Research and development plans for further improving low-cost training technologies also are described.
